Way to merge email and member fields? #1267

Motivation

Adding this as a placeholder so we don't forget. Basically, now that we can send invites from email fields, we're having an issue where sometimes we want to initiate an action from something that's just an email field, but once the account is created, do the rest off of the workflow off of a member field. There's also just general admin confusion about how invites are now working via actions off of email vs. member fields.

So, could use a discussion about how we can streamline this a bit.
